Question

Who invented the ‘computer laptop’?

• A. Arthur Wynna - USA
• B. Q. Daimler - Germany
• C. Sinclair -Britain
• D. None of the above

Answer 1

The Correct Option is D

Step 1 — Understand the question:
We are asked about the inventor of the “computer laptop.” Laptops are portable personal computers that were developed after years of innovation in computer miniaturization and portability. Unlike some inventions that can be credited to one single person, the laptop evolved through contributions of many individuals and companies.

Step 2 — Early portable computer attempts:
• In 1975, the IBM 5100 was introduced — one of the first portable computers, but it was still bulky.
• In 1981, Osborne 1 was released by Adam Osborne. This is often considered the first commercially successful portable computer, but it was not yet a true “laptop” (it weighed about 11 kg).

Step 3 — Move towards the real laptop:
• The Grid Compass 1101, designed by Bill Moggridge in 1979 and released in 1982, is considered the first true laptop. It had the clamshell design (screen folding over the keyboard) that is still used today.
• Later, in the mid-1980s, laptops became more practical with products like the Toshiba T1100 (1985), which popularized laptops globally.

Step 4 — Why the answer is “None of the above”:
Since the development of the laptop computer was not the work of one person alone and multiple contributors like Adam Osborne, Bill Moggridge, and companies like Toshiba all played roles, the invention cannot be credited to a single name in a simple option list. Hence, the correct choice is “None of the above.”

Step 5 — Conclusion:
The laptop as we know it today was a result of multiple innovations over time rather than the invention of one single person.

Final Answer:
The correct option is (D): None of the above.
